About Me

Hello World. Welcome to sysadminas Cloud Blog.

I’m Andrej Trusevic, a Cloud Engineer focused on Kubernetes and Azure. I design and operate secure, scalable cloud-native infrastructure — from cluster architecture and GitOps delivery pipelines to security tooling and AI-assisted automation.

Certifications

I’m a Golden Kubestronaut — CNCF’s recognition for practitioners who have earned every available Kubernetes and cloud-native certification. It’s the highest tier in the Kubestronaut program, requiring a full sweep of CNCF credentials including CKA, CKS, CKAD, and the growing set of associate-level certifications (CGOA, CCA, CAPA, PCA, ICA, CNPA, KCA, and others).

What I Work With

• Kubernetes & AKS — cluster design, upgrades, and day-2 operations on Azure Kubernetes Service
• GitOps — Flux and Helm-based delivery pipelines for declarative workload management
• Security — Trivy, Falco, Consul, policy enforcement, and supply chain hardening
• AI-assisted DevOps — encoding operational knowledge into Claude Code skills and agents to automate routine platform engineering work

About This Blog

sysadminas.eu documents what I learn on the job. Posts cover practical Kubernetes and Azure topics, GitOps patterns, security tooling, and how AI is changing day-to-day platform engineering work. I write to share what I pick up and to give back to the community that has taught me most of what I know.
